Display Hours and Rate on assignment level in custom payslip for UK

Summary:

We want to display Hours and Rate value on assignment level section in payslip but currently it is only coming in GLB_PAY_ARCH_PR_UNITS_X_RATE and GLB_PAY_ARCH_PR_HOURS_X_RATE group which are on payroll relationship level. We checked the "Payroll Archive" extract definition. In the extract we checked there is group for assignment level hours by rate but it is defined by procedure not balance group. The data group tag is GLB_PAY_ARCH_PAY_ASG_HBR, so can you please advice what setup is required to bring the value in the GLB_PAY_ARCH_PAY_ASG_HBR group for the balances on hours by rate.
